An introduction to the difference between distance traveled and displacement.

Using a one-dimensional number line to visualise and calculate distance and displacement.

In this unit you will learn:

• About the turning effect of forces
• Turning effects are called moments
• Understand that regular and irregular shaped objects have a centre of gravity
• An objects centre of gravity determines if it is in a stable, neutral, or unstable equilibrium

Managing time involves accurately predicting how much time it will take to do a task, and then setting aside that amount of time to complete it. Managing time is much more difficult than it may seem, which is why there are entire courses of study and research on the best approaches. But if you develop a method to undertake each component, you’ll be successful.

This video explains how pie charts can be used to display data in a more 'user-friendly' way.

Using position-time graphs and number lines to find displacement and distance traveled.

Worked examples finding displacement and distance from position-time graphs.
